What to know about Levitating molten metal on ISS could refine ultra-strong metallic glass

Researchers from Saarland University are conducting experiments on the International Space Station to study the properties of metallic-glass alloys using levitating droplets in microgravity. The study aims to obtain high-precision data on surface tension and viscosity to improve the development of ultra-strong materials for aerospace and industrial applications.

What happened

Levitating molten metal on ISS could refine ultra-strong metallic glass Gaby Clark Scientific Editor Robert Egan Senior Editor The research team led by materials scientist Ralf Busch from Saarland University is preparing for its first science-in-space mission.

Why it matters

If everything goes to plan, from 31 August the researchers will spend one week remotely studying metallic-glass alloys in experiments carried out on board the International Space Station, ISS.

Common ground

Working with the European Space Agency, ESA, and the German Aerospace Center, DLR, the team will investigate the properties of these alloys using hot, levitating droplets.
